` PENNSYLVANIA.

WATER-METER.

SPECIFICATION forming part of Letters Patent No. 783,298, dated February 21, 1905. Application filed April 13.1904. Serial No. 202,931,

To ril/ZZ whom, it may concern:

Be it known that we, ELMER H MCCREARY and GEORGEA. N IEMAN, citizens of the United States, residing at Beaverfalls, in the county of Beaver' and State of Pennsylvania, have invented a new and useful improvement in Water-Meters, of which improvement the following is a specification.

This invention relates to an improved water-meter; and it consists in the certain details of construction and combination of parts, as will be fully described hereinafter.

ln the accompanying drawings, Figure 1 is a central side sectional elevationl of our improved water meter, the same being construeted and arranged in accordance with our invention, the said section being taken on the line X X of Fig. 2. Fig. 2 is a plan view of the same, the lid or cover being removed and a part of said view being shown in section. Fig. 3 is an enlarged sectional end elevation of one of the wings or hinged propellers, showing the manner in which the same is mounted in the rotatable frame. Fig. 4 is a front sectional elevation of the same, said section taken on the line Y Y.

To construct a water-meter in accordance with our invention, we provide an annular' casing 1 of a suitable size and form of construction and fit the same with a lid or cover 3, secured thereto by means of bolts 2, and the said casing formed with a water-inletl and an outlet 14. Formed integral with the casing 1 and in the bottom thereof` is a semicircular partition 4, arranged a short distance from the inner wall of said casing and located opposite the inlet and outlet openings.

Arranged in ball-bearings 7 in a vertical position at the center of the casing 1 is a shaft '6, carrying a horizontal disk 8, having an enlarged periphery 9 to form bearingsockets for a series of hinged wings 11, arranged radially and at equal distances the one from the other. Each of these wings consist of a cylindrical portion 10, adapted to fit neatly in corresponding recesses formed in the enlarged periphery of the disk 8, and an outwardly-projecting blade 11 of a size and shape similar to that of a cross-section taken through the chamber 5 formed by the partition 4, as will be seen by reference to Figs. 3 and 4 of the drawings.

Mounted in a suitable bearing 16, formed integral with the lid or cover 3, is a shaft 17, having attached to its inner end a toothed wheel 18, which when brought in contact with a pin 19, secured to the face of the rotatable disk 8, will cause the said toothed wheel to revolve a limited distance. This shaft 17 operates the usual registering mechanism common in various styles of water-meters now in use.

In operation the water entering the inletpipe 15 under pressure will strike the wing 11 directly opposite, propelling the same in the direction of the outlet 14, thereby causing' the disk 8 to turn and at each complete revolution operate the shaft 17, connected to the indicating-dials of the meter. This movement is accomplished by thel peculiar manner in which the wings are hinged, which when operated upon by the force of the water will be heldin a vertical position by coming in contact with the shoulder 13, as shown in dotted lines at Figs. 3 and 4, or folded within a recess 12.

Modifications and changes may be made in the details of construction without departing from the spirit of the invention.

Having thus described our invention, what we claim, and desire to secure by Letters Pat` ent, is-

1. The herein-describedV water-meter, consisting of the shell 1, provided with suitable inlet and outlet connections and water-tight cover 3, a semicircular integral lpartition 4 formed with said shell and located opposite the inlet and outlet openings, a shaft 6, centrally mounted within the shell, a disk 8 earried by said shaft, said disk having an enlarged periphery, a series of wings 11, hinged to said disk adapted to pass through and close the chamber 5 formed by said partition, a counter shaft 17, connected to indicatingdials, a toothed wheel mounted upon the inner end of said shaft, and a means connected to the disk 8 to contact with said toothed wheel at each revolution, whereby the quantity of water passing through the shell may be measured, as described.

2. In a water-meter, the combination with a casing having an arc-shaped partition at one side constituting a waterway, of a disk jour-` naled in the casing below the top thereof, indicator-actuating means interposed between the disk and the top of the casing, and swinging wings carried by said disk, substantially as described.

3. In a water-meter, the combination of a casing having an arc-shaped partition on its bottom forming awaterway between said partition and the outer wall of the casing, a plug screwing into .the center of the bottom of ELMER H. MCCEEAEY. GEORGE A. NIEMAN.
